I appreciate this change. I wonder however why not use the
CONFIG_ENV_VARS_UBOOT_CONFIG + CONFIG_ENV_VARS_UBOOT_RUNTIME_CONFIG and
the corresponding env vars.
In include/env_default.h we define 'board_name' to the name of the
board. This could then easily be used to switch the required DTB.
I think the CONFIG_ENV_VARS_UBOOT_CONFIG should only be used for boards
where the name is fixed (like some older EK's). Here the runtime config
is right, but let's use the $board_name, Ok?
